I've cleaned up and pushed the above suggestions to my staging tree at https://git.lede-project.org/?p=lede/nbd/staging.git;a=summary

I've left out the removal of CONFIG_AR8216_PHY, since it doesn't make any sense to me. This driver is still being used.

Please test that tree and let me know if it works for you.
Thanks
